(B) Comparison of the number of scaffolds (X axis) and the proportion of the genome covered by the assembled scaffolds (Y axis). The 23 largest pig-tailed macaque scaffolds (blue line) cover 90% of the genome. The red line presents the scaffold sizes of human genome (GRCh38) assembly, and the green line is the current assembly of pig-tailed macaque on NCBI (Mnem_1.0). (C) Karyotype of the pig-tailed macaque chromosomes. This high-quality assembly allowed us to identify large-scale structural variations compared to the human genome. In addition, we GSK744 (S/GSK1265744) annotated the genome using RNA sequencing (RNAseq) and proteomics data from induced pluripotent stem cell (iPSC) lines derived from the peripheral blood mononuclear cells (PBMCs) of the same animal. Using this annotation, we inferred phylogenetic relationships among pig-tailed macaque (set up (Ma2) represents a considerable improvement in quality and scaffold size set alongside the currently available set up (Mnem_1.0) and can be compared in quality towards the research human being genome (Fig.?1B). Utilizing a mix of linked-reads (10X Genomics Chromium Program) and closeness ligation (HiC)-centered scaffolding we produced a genome set up of a complete amount of 2.92 Gb having a scaffold N50 of 127.5 Mb. The 23 largest constructed scaffolds cover 90% of the complete pig-tailed macaque genome. We karyotyped the iPSCs through the scholarly research pet. As the pig-tailed macaque offers 20 pairs of autosomes and a set of sex chromosomes (Fig.?1C) [14], each scaffold represents an individual chromosome. In regards to to scaffold sizes, the brand new pig-tailed macaque genome set up (Ma2) is comparable Rabbit Polyclonal to C9orf89 to that of the human genome, which has been constantly improved over the past 20 years since its initial assembly [15]. Using only the linked-reads method we obtained an assembly with scaffold N50 of 8.6 Mb. However, using a combination of linked-reads and proximity ligation, we were able to increase the scaffold N50 to 127.5 Mb. Moreover, we observed significant improvements in reducing the extent of gaps in the assembled scaffolds. To evaluate the quality of our assembly, we ran BUSCO 3.0.2 [16] using the OrthoDB mammalia database. We found 91.9% of complete BUSCO genes in the new pig-tailed macaque (Ma2) assembly, of which 89.0% were single-copy, 2.9% duplicated, 3.9% fragmented, and 4.2% missing (Supplementary Fig. S1A). Comparison of the new pig-tailed macaque genome with the human and rhesus macaque genomes reveals both extensive synteny conservation and genome rearrangements Pig-tailed macaques have 20 pairs of autosomes and 1 pair of sex chromosomes (Fig.?1C) [14]. Using the new genome assembly of the pig-tailed macaque, we performed synteny comparison of chromosomes between rhesus and pig-tailed macaque and human and pig-tailed macaque. Synteny analysis among the pig-tailed and rhesus macaque (rheMac 8.0.1) indicated a high level of homology between the two (Fig.?2BCD). Synteny between human and pig-tailed macaque genomes showed large structural rearrangements like a divide of chromosome 7 from the pig-tailed macaque into chromosomes 14 and 15 in the individual genome (Fig.?2A, ?,E,E, and F). Furthermore, chromosomes 12 and 13 from the pig-tailed macaque both align onto individual chromosome 2 (Fig.?2A). We further looked into the examine pairing from the closeness ligation libraries for every of the chromosomes to validate the noticed huge structural rearrangements. The mapping of linked-read HiC data on chromosomes 7, 12, and 13 of pig-tailed macaque facilitates the precision and reliability from the determined rearrangements (Fig.?3A and?B).
